Vessels
Beer is made by moving it from one vessel to the next and waiting. Four of them, in the order the beer meets them.

Mash
The Copper
Grain is not beer. Water is not beer. The copper is where the argument between them is settled — a vessel of thirty litres, held at temperature for an hour, until the malt surrenders its sugar and the wort runs clear. Beside it a second vessel, twenty-five litres, holds the sparge water hot. The copper cannot heat the mash and the sparge at once.
Then the boil. Sixty minutes, and the hops go in on a schedule each beer decides for itself, and the room turns humid and smells of bread. Everything after this is waiting.

Ferment
The Tun
The wort goes into the tun, the yeast goes in after it, and from there the beer is left alone. Some finish in four days. Some take three weeks. The tun does not mind which, and neither does the calendar — there is room between one feast and the next.
The tun stands in a box that holds whatever temperature is asked of it, from sixteen degrees to thirty-two, because the yeasts do not agree with one another. The airlock ticks, and there is nothing else to do here.

Condition
The Cellar
Nine litres to a keg, and eight kegs, three of them cold at a time. Two of the three taps hold steady — one light beer and one dark, brewed twice a year each, always there. The third turns with the year: winter, spring, summer, fall. Nine litres is thirteen weeks, which is a season.
Elsewhere in the cold, two kegs wait for their feasts. The gas sits at eight tenths of a bar and is left alone. The cellar's only virtue is that nothing happens in it.

Keep
The Reliquary
Not everything goes to the taps. Bottles are filled from the keg, never from the tun, six at a time under gas. What is kept is the same beer that was poured. Each takes a gold crown and a printed label: the saint, the feast, the year.
The kegs are for drinking. The bottles are for keeping. A bottle with a date on it is a small reliquary, and a shelf of them is a calendar that can be held.
